Memory Game Waves definitionsOnline version match the term to the definition by Dilini Wijayasinghe Waves which transfer energy Wave, of which the particles oscillate parallel to the energy The length between two similar points in two consecutive waves Waves, of which the particles oscillate perpendicular to the energy 1 wave produced by the source per second An imaginary line drown through the crest of a wave perpendicular to the energy flow Angle subtended at the centre of a circle when the path of an oscillating particle of a wave is represented by the circumference of the circle. The time taken by a source to produce one wave Maximum displacement of a particle from the equilibrium point The number of waves produced per unit time by a source The distance moved by the particle in a particular direction from the equilibrium point Distance moved my energy of the wave in a unit time
